SAFETY-SWITCH.

$PECIFICATION formingpart of Letters Patent No. 376,177, dated January10, 1888.-

Application filed January 13, 1887, Serial No. 221,206. (No model.) I

To Ml whom, it may concern.-

Be it known that 1, JOHN B. BATT, of Williamsville, in the county ofErie and State of New York, have invented new and useful Improvements inSafety-Switches, of which the following is a specification.

This invention relates to that class of safetyswitches in which theswitch'rails are moved automatically .to the proper position by thewheels when the latter approach the free ends of the switch-rails on atrack for which the switch is misplaced.

My invention has for its object to produce a simple and durable switchof thiskind, which guides the wheels securely and which is easily keptin order.

My invention consists of the improvement, which will be hereinafterfullyset forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a top plan view of my improvedswitch set for the main track. Fig. 2 is a similar view, showing theswitch set for the side track. Fig. 3 is a Vertical cross-section inline a: m, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A A and B B represent the stationary rails of the main track.

' O 0 represent the movable switch-rails pivoted near the ends of therails A A.

D Drepresent the rails of the siding ar; ranged alongside the main railsB B and terminating in line with the same.

E E represent guard-rails arranged on the inner sides of theswitch-rails O O, and rigidly secured thereto by bolts 6 andintermediate blocks, f, or other suitable means, so as to move with'theswitch-rails. The latter and the guard-rails are supported on platesupon the ordinary cross-ties and connected to a crossbar, g, which isoperated by a shifting The front portions, h h, of the guardrails E Eextend forwardly beyond the ends of the main In the position of theparts represented in Fig. 1 the switch is set for the main track and theguard-rail E rests with its curved front portion, h, against the innerside of the side rail,D. WVhen a locomotive or car approaches the switchon the side track, D D, for which the switch is misplaced, the wheelrunning on the side track, D, strikes with its flange running on themain rail B strikes with its flange against the front curved portion, h,of the guardrail E, and moves the switch-rails and guard-rails laterallyto the position rep resented in Fig. 1, thereby setting the switch forthe main track.

I am aware that it is not new to connect the guard-rails with theswitch-rails in such manner that a wheel striking the projecting curvedend of the guard-rail will shift the switch, as in Patent No. 267,308,November 7, 1882, and that switch and guard rails have been providedwith lateral flanges, as in Patent No. 175,287, March 28, 1876, and I donot claim such construction.

I claim as my invention- The combination, with the main rails B B andside rails, D D, of the movable switchrails O O, guard-rails E E,provided with inwardly-curved front portions, 71 h, blocks f, arrangedbetween the guard -rails and the switch-rails, and bolts 6, whereby theguardrails and blocks are rigidly secured to the switch-rails,substantially as set forth.

\N'tness JOHN B. BATT.
